The error codes registered in the computer's software can be recorded in the
SYSMAC CS1 Board's Error Log Area.

The SYSMAC CS1 Board is equipped with the same remote I/O functions as a
CS1W-DRM21-V1 DeviceNet Master Unit. The remote I/O functions can be
used to transfer data between the Board and Slaves without special program-
ming in the Board.
In addition to the Master function, the Board is equipped with an explicit messag-
ing/FINS messaging function (message communications) and a Slave function
(Remote I/O Slave capability).
Note 1. When using a DeviceNet Configurator to make DeviceNet settings for the
Board, select the "CS1W-DRM21" EDS file.
2. This manual does not provide detailed information on DeviceNet functions.
Refer to the CS/CJ Series DeviceNet Unit Operation Manual (W380) for de-
tails.
The following table shows the maximum number of I/O points and Slaves that
can be connected to the SYSMAC CS1 Board.
DeviceNet Configurator not being used
2,048 points (64 input words and 64 output words)
or
16,000 points (500 input words and 500 output words)
32 points (1 input word and 1 output word)
or
3,200 points (100 input words and 100 output words)
64 Slaves
The communications distance in a DeviceNet Network is restricted by the baud
rate, as shown in the following table.
Baud rate
500 kbps
250 kbps
125 kbps
All slaves are allocated words in the I/O memory of the CPU Unit Module to
which the Master Unit is mounted. Words are allocated by fixed allocation or
user-set allocation.
